Description
Additional information

The Siemens 6AV6244-1BC10-0BX1 is an Operator Panel (OP 177B) belonging to the SIMATIC HMI series, designed for machine-level visualization and operator control tasks. This unit provides a monochrome STN display and is part of the SIMATIC HMI comfort and basic panel lineup, intended for use with Siemens SIMATIC PLCs and third-party controllers. The OP 177B offers a compact and robust design suited for panel mounting in industrial environments.

The 6AV6244-1BC10-0BX1 features a 5.7-inch STN monochrome display with a resolution of 320 x 240 pixels (QVGA) and supports touch and key-based operation through integrated function keys. It communicates via MPI, PROFIBUS DP, and RS-422/RS-485 interfaces, enabling direct integration into SIMATIC S7 and S5 controller networks. The panel includes 512 KB of user memory for project data and is configured using WinCC flexible 2005 or later engineering software. It operates on a 24 V DC supply and carries CE and UL certifications.

The OP 177B is widely deployed in machine building, packaging, material handling, and process automation applications where a cost-effective, reliable operator interface is required. Its compatibility with PROFIBUS DP makes it suitable for distributed automation architectures, and its rugged construction allows installation in demanding industrial environments. The panel is particularly common in retrofit and modernization projects where integration with existing SIMATIC S7-300 and S7-400 controller infrastructure is needed.

Common Error Codes and System Events

Event ID: 10000: Configuration error detected during startup; project data on the panel is corrupted or incompatible with the current firmware version.
Re-transfer the project using WinCC flexible. Ensure the project version matches the panel firmware version.
Event ID: 20000: Communication connection to the PLC has been lost or cannot be established.
Check MPI or PROFIBUS DP cabling and termination resistors. Verify PLC address settings match the panel configuration.
Event ID: 40000: Tag read/write error; the panel cannot access a configured PLC data address.
Verify the PLC tag addresses in the WinCC flexible project. Ensure the PLC program contains the referenced data blocks and variables.
Event ID: 50000: Overflow of the alarm buffer; too many alarms have been generated and the buffer capacity has been exceeded.
Acknowledge and clear pending alarms. Review the alarm configuration to reduce unnecessary alarm triggers.
Event ID: 70000: System memory low; available memory for runtime operation is insufficient.
Reduce the project size, limit the number of active screens or variables, and re-transfer the optimized project to the panel.
Event ID: 110000: Firmware update error; the firmware transfer to the panel was interrupted or the firmware file is incompatible.
Restart the panel in transfer mode and repeat the firmware update using the correct firmware version for the OP 177B.

Frequently Asked Questions

What engineering software is required to configure the OP 177B (6AV6244-1BC10-0BX1)?

The OP 177B is configured using Siemens WinCC flexible 2005 or later versions. Projects are transferred to the panel via MPI, PROFIBUS DP, or a USB/serial connection using a PC adapter.

Which Siemens PLCs are compatible with this operator panel?

The OP 177B is compatible with SIMATIC S7-200, S7-300, S7-400, and S7-1200 controllers via MPI or PROFIBUS DP. It also supports communication with SIMATIC S5 PLCs via the RS-422/RS-485 interface.

What is the supply voltage for the 6AV6244-1BC10-0BX1?

The panel operates on a 24 V DC supply voltage. The power consumption is a maximum of 8 W under normal operating conditions.

What is the front panel protection rating of the OP 177B?

The front panel of the OP 177B carries an IP65 protection rating, making it resistant to dust ingress and low-pressure water jets, suitable for industrial panel door mounting.

Can the OP 177B communicate over PROFIBUS DP?

Yes, the OP 177B supports PROFIBUS DP communication, allowing it to connect to SIMATIC S7-300 and S7-400 PLCs as well as other PROFIBUS-compatible controllers in distributed automation systems.

Troubleshooting

Display remains blank after power is applied

Measure the 24 V DC supply voltage at the panel power connector. Check for blown internal fuses or wiring issues at the terminal block.

Ensure the 24 V DC supply is within tolerance. If supply voltage is correct and the display remains blank, the internal power supply board or backlight may be faulty and the unit should be sent for repair or replacement.

Panel shows 'No connection to PLC' or communication error on startup

Check the MPI or PROFIBUS DP cable connections and verify that bus termination resistors are correctly placed at both ends of the network. Confirm the PLC address configured in the WinCC flexible project matches the actual PLC station address.

Correct any wiring faults, ensure proper bus termination, and verify address settings in both the panel project and the PLC hardware configuration. Re-transfer the project if configuration changes are made.

Touchscreen or function keys do not respond to input

Perform a visual inspection of the keypad membrane and touch overlay for physical damage. Attempt a panel restart to rule out a software lockup condition.

If a restart does not resolve the issue, recalibrate the touch interface through the panel's system settings menu. If keys remain unresponsive, the keypad membrane or touch controller hardware may require replacement.

Project transfer from PC to panel fails or times out

Verify the PC adapter cable type and COM port settings. Ensure the panel is set to transfer mode (accessible via the Start Center on the panel) and that the correct communication interface is selected in WinCC flexible.

Use a compatible Siemens PC adapter (USB or MPI/DP adapter), confirm the baud rate settings match on both sides, and retry the transfer. Update WinCC flexible to the latest service pack if transfer errors persist.

Panel restarts repeatedly or enters a boot loop

This may indicate a corrupted project or firmware on the panel. Attempt to access the Start Center during boot by pressing the appropriate key combination to prevent automatic project startup.

From the Start Center, perform a factory reset or re-transfer a valid project and firmware version using WinCC flexible. If the boot loop continues after re-flashing, the panel memory may be defective and hardware repair is required.
